Mono
To defuse the situation a bit: Mono Mono is a good piece of software which I like and use quite often. The catch is that I don’t think Mono’s stable yet. Some parts of mono are, others are not. As the term ‘Mono’ is normally associated with the whole suite (compiler, library, tools) this is, from my point of view, acceptable.
Dissension on implementation details is permitted (even for open source software), I think.
